attached to horn bodies by soldering and similar methods, but these methods have been Certain disadvantages have become apparent in the horns produced by these methods especially when mounted on motor vehicles. For example, vibration and roadshocks have been transmitted to the horns when so mounted so that in time the bells have tended to become loose, and in cases have been lost.

In the present invention the 'manufactur ing costs are materially reduced and the: horns producedby this-method have the horn bells so attached to the horn bodies that they successfully resist vibration and road shocks.

One specific embodiment of the principles of the invention is illustrated in the drawing, wherein:

Fig. 1 is a fragmentary sectional view of a horn body with a horn bell permanently attached to the outer end thereof.

Fig. 2 is a fragmentary sectional view on an enlarged scale showingthe lapped relation of the horn bell to the'horn body, when the former is inserted in the latter. The broken lines depict a position of the horn bell during insertion.

Fig. 3 is a transverse sectional view taken along line 83 of Fig. 2 showing the relation of the horn bell to thehorn body when the former is inserted in the latter.

Fig. 4 is a fragmentary sectional View on an enlarged scale showing the relation ofthe.

horn bell to the horn body whenthe part-s are fully assembled, and,

Fig. 5 is a transverse sectional view taken centrally of Fig. 4' showing the interengagement of the horn parts.

As shown in Fig. 1 the tapered section or horn body 1 is formed with a peripheral bead 2 on the larger end 3 of-body' 1. The inner surface of the bead 2 is knurled or transversely serrated as at 4. A shoulder 5 is tion. 1, I ,1 The horn body and horn bell having been formed on the horn bodyiinmediately ad-' Jacent and as a part of the bead 2 during 7 the beading operation andis of less diameter than theouter end of said bead for a purpose to be hereinafter described.- 1

1 A bell section or horn bell 6 of any'suiti Y ableshape is mounted inthe horn-body by means ofa peripheral bead 7 that is complementary. to the peripheral bead 2 and'is' formed 'on' the smaller end 8. of saidbell. Said bead is knurled or serrated as at9 so thatthe outer surface of bead :7 'interengages with; the innersurface i of bead 2 and a positive firmer joint betweenthe horn body. and horn bell results.-

The

material of theflange 10 not only provides a stop to limit the insertion of the bell into the Thehorn pbody'l is formed from atube the same or a separate opera. 7

body, but also provides the necessary material for expansion when the head 7 is formed without disturbing the relationofthe bell with respect to thehorn, as well as serving.

' as an abutment or guide for the expanding tool prior to the formingof bead 7. The. lapped relation of the horn body and horn bell may be maintained byplacing the body 1 in a holding die 11,- (partially shownuin" broken lines in Fig. 5)

for giving the bead 2 external support, and then inserting an'eip. panding tool or die 12',- (partially shownin y I i 1,868,250 I broken lines in Fig. 5), within the bell and expanding it to force the lapped portion of the bell which is immediately adjacent the, flange 10 into intimate contact with the inner 5 surface a of the bead 2. Thus, the complementary. bead 7' is formed on the bell and the intimate contact between the beads i's'j obetained. Toinsurethis intimate contact be-i tween the beads the operative face 14 of the v V we expanding'die 12'm'ay'be' knurled or serrated in a manner similar to that of the surface 45" whereby a transverse section through. th a. g g beads simulates that shown in Fi 5 i From a perusal of the foregoingedescri p v tion it will be apparent that a horn and m What is claimed isiz' method of making the same has been pro vided to efiiciently produce two-part horns having a permanent joint that will withstand vibration and road shocks; 7
